NASA’s Perseverance rover is on the verge of changing humanity’s future. Just over a year after touching down on the red planet, Perseverance is embarking on the most demanding part of its mission to date – striking out at top speed for the sites most likely to house signs of life. To succeed, the team must overcome epic challenges and take Perseverance into uncharted territory: going further than any other rover and traversing jagged terrain - all on a hostile planet 300 million kilometres away from the Earth.
In this unique television event for BBC Two and iPlayer, Professor Brian Cox fulfils a childhood dream by going behind the scenes at Nasa’s Jet Propulsion Laboratory (JPL), mission control Mars.
Brian says: "The nature of origin of life is one of the great unanswered scientific questions. Here on Earth, life was present around 3.8 billion years ago, but the evidence for how it arose has been weathered away and erased by the geological activity of our planet. Mars, however, is a different story. It was decidedly Earth-like at the same time, with rain, rivers and lakes, but it soon entered a geological deep-freeze from which it never emerged. If there were Martians, the evidence for their emergence from the geology and chemistry of a young, active world may be far better preserved. The Perseverance Rover, and the Mars Sample Return missions to follow, may therefore answer a deeper question even than ‘Is there life on Mars?’ They may reveal how life begins across the Universe, including here on Earth, and give us unique insight into our own origins."
In 1980 a young Brian Cox wrote to the Jet Propulsion laboratory asking for photos from Voyager and the Viking mission to Mars. These were a source of inspiration that set him on the path to becoming a physicist.
Now, over 40 years later, he has been granted privileged access to JPL – to witness the workings of the mission as it guides the Perseverance rover and the Ingenuity helicopter (the first powered aircraft we have even sent to another planet) across the surface of Mars.
Over the course of a week he joins the team as they navigate follows the rover’s every move across the floor of Jezero crater towards the remains of an ancient river delta – that may contain the evidence of ancient life on Mars.
In the process, Brian will reveal how the mission could potentially transform our understanding of life not just on Mars but Earth as well. This is the inside story of a pioneering quest into the unknown.

得重新审视engineer这个词了，太ENGINEERING了！从science fiction到science fact，缺的是一群致力于解决问题的engineer。方案可能会很复杂，复杂到让人觉得像是在扯淡，但现在的科技对于即便几十年前的人来讲，它似乎就是荒谬且魔幻的。engineer得做DARE MIGHTY THINGS，不怕天方夜谭，只要每一个细节都一一实现。（并测试……单元测试……集成... 得重新审视engineer这个词了，太ENGINEERING了！从science fiction到science fact，缺的是一群致力于解决问题的engineer。方案可能会很复杂，复杂到让人觉得像是在扯淡，但现在的科技对于即便几十年前的人来讲，它似乎就是荒谬且魔幻的。engineer得做DARE MIGHTY THINGS，不怕天方夜谭，只要每一个细节都一一实现。（并测试……单元测试……集成测试……测试可太重要了，只要测得全，就没有不敢上的线） 在标记着RGB码的纸袋上用蜡笔上色，涂抹出第一幅传回来的火星表面图片，还有比这更艺术的艺术吗？没有。 最后，坐等2031年火星样本回收。JPL确实是严谨且敢想敢干啊！ （出bug导致第二天火星车没有动，且被拍到了纪录片里……大写的尴尬…） (展开)

这部纪录片在教授的系列里算是比较乏味的，但教授总是抛出话题性问题，引人深思：我们在宇宙中是孤独的吗！

油管可以直接看。其实也没说啥，就是感觉人类太渺小了，看到第六天的时候我以为正好赶上落地收石，结果还要好几年。毕竟名字跟着上了Mars还是关心一下哈！教授虽然是肉眼可见的沧桑以及发福，但是苹果肌自然光泽膨亮
